Thanks, everyone. I never expected the question to generate such a huge response. A lot of really good info. I think I'll give Simple Green a go and see how the figure fares.
Wow. Thanks rotokirby, that's some great info. So really, over time, as degradation occurs, vinyl toys may just get a little firmer and less maleable so to speak.. and the toys made of clear vinyl may get a bit cloudier and lose some transparency. And that in itself will probably take decades. Not all that bad.
